Duke Energy power plant imploded
Duke Energy Progress' demolition specialist recently imploded the retired W.H. Weatherspoon Plant as part of the company's longstanding effort to transition to cleaner energy sources.
After more than four months of demolition activity at the site, this milestone dramatically transforms the landscape where the coal plant had operated safely and reliably for more than 60 years.
Duke Energy's ultimate goal for retired sites such as Weatherspoon is to dismantle the equipment and buildings, and restore the site to ground level. The implosion event at Weatherspoon allows the company to complete the demolition work and begin restoring the land.
Restoration involves filling, grading and seeding the land to prevent erosion and protect water quality. The company plans to complete this phase by mid-2014 and will continue to own and steward the land.
Duke Energy has invested $9 billion in the last decade in building some of the cleanest natural gas and coal plants possible, with high efficiency and state-of-the-art emissions controls.
This allows the company to retire nearly 6,800 megawatts (MW) of older coal and large oil-fired units. Nearly 6,300 MW of the capacity Duke Energy will retire is coal, which represents 25 percent of its coal fleet. By the end of 2013, Duke Energy will have retired more than 3,800 MW of this older coal capacity.
These retired plants will enter the decommissioning program and will move through a demolition process similar to Weatherspoon's.
Hydrostor receives $4m funding for A-CAES facility in Canada
Hydrostor has received $4m funding to develop a 300-500MW Advanced Compressed Air Energy Storage (A-CAES) facility in Canada.
The funding will be used to complete essential engineering and planning, and enable Hydrostor to plan construction.
The project will be modeled on Hydrostor’s commercially operating Goderich storage facility, providing up to 12 hours of energy storage.
Hydrostor’s A-CAES system supports Canada’s green economic transition by designing, building, and operating emissions-free energy storage facilities, and employing people, suppliers, and technologies from the oil and gas sector.
The Honorable Seamus O’Regan, Jr. Minister of Natural Resources, said: “Investing in clean technology will lower emissions and increase our competitiveness. This is how we get to net zero by 2050.”
A-CAES has the potential to lower greenhouse gas emissions by enabling the transition to a cleaner and more flexible electricity grid. Specifically, the low-impact and cost-effective technology will reduce the use of fossil fuels and will provide reliable and bankable energy storage solutions for utilities and regulators, while integrating renewable energy for sustainable growth.
Curtis VanWalleghem, Hydrostor’s Chief Executive Officer, said: “We are grateful for the federal government’s support of our long duration energy storage solution that is critical to enabling the clean energy transition. This made-in-Canada solution, with the support of NRCan and Sustainable Development Technology Canada, is ready to be widely deployed within Canada and globally to lower electricity rates and decarbonize the electricity sector."
The Rosamond A-CAES 500MW Project is under advanced development and targeting a 2024 launch. It is designed to turn California’s growing solar and wind resources into on-demand peak capacity while allowing for closure of fossil fuel generating stations.
Hydrostor closed US$37 million (C$49 million) in growth financing in September 2019.
